Definitions

  • the invention relates to a combination of a cross member and a side member, the side member being provided on both sides with a supporting flange having an upstanding edge and an upper flange which projects laterally with respect to the vertical web of a side member, the cross member having at least one longitudinal end hook-shaped end to the hook is provided over the upstanding edge of the side member.
  • this cross member after hooking a cross member over the edge of the longitudinal member, this cross member can have such freedom of movement upwards that it can get out of position. This can occur in particular if a cross member has only been mounted on one end in a side member and the other end is freely cantilevered on a tubular steel support. This can lead to undesirable situations for the people on the floor formwork panels.
  • the upper side of the cross member is on a fixed plane with respect to the upper side of the side member. If the upper side of the cross member lies in the same plane as the upper side of the side member, the formwork panels are placed on the side member. If the upper side of the cross member is lower than the upper side of the side member, formwork panels of a certain thickness are placed between the side members so that the top side of the formwork panels is in the same plane with the top side of the Longitudinal beam. A combination of the two solutions is not possible in the patent application mentioned.
  • the invention now aims to provide a construction in which the cross member can no longer get out of position with respect to the side member, which generally provides an even greater level of safety for the persons on this support construction, and this construction is also particularly suitable for to arrange a cross member in a clearly secured manner between two attached, parallel side members.
  • this is now achieved with a construction which is characterized in that the end of the cross member is designed such that this carrier can be hooked over the edge of the supporting flange of the side member in a first tilt position rotated about its longitudinal axis and by twisting around it Longitudinal axis can be brought into a second tilting position in which the cross member is secured between the upstanding edge of the supporting flange and the upper flange of the longitudinal member.
  • FIG. 1 shows a combination of side members 1 with cross members 2 placed between them
  • FIG. 2 relates to a combination of cross beams 2 which are placed on the longitudinal beam 1 at one end and the other end is supported by a square timber 3 with tubular steel supports 4,
  • FIG. 3 shows the placement of a cross member in a longitudinal member, specifically in its unsecured position
  • Figure 3a is a cross-section along A-A of Figure 3
  • FIG. 4 shows the placement of a cross member in a side member after the cross member has been rotated by 90 ° about its longitudinal axis, as a result of which the securing has been achieved below the upper flange of the side member.
  • Figure 4a shows a cross section along BB from the Figure 4 is
  • FIG. 5 shows a side member which can be hooked into the side member at one end and which can then be moved upwards into the vertical plane at its other end, as a result of which the end of the cross member comes below the upper flange of the side member,
  • FIG. 6 shows in perspective an embodiment of one end of the cross member to be fastened in the longitudinal member
  • Figure 7 illustrates the placement of a cross member in a side member, wherein the cross member beam can be rotated by 180 ° with respect to the end of the member, whereby the upper side of the cross member comes into a different plane with respect to the upper side of the side member.
  • support for a floor formwork is formed from a grid of longitudinal beams 1 and cross beams 2.
  • the whole is held at a certain height by, for example, steel pipe supports, not shown, and is covered by plate material.
  • the longitudinal member has a web with a continuous support flange 5 on both sides with a raised edge 6.
  • the cross member 2 has an end which is provided with a hook-shaped head 15 which can hook around the upstanding edge 6 of the side member (FIG. 5). The cross member remains in position in that the end 7 is located below the projecting flange 9 of the side member.
  • the formwork will protrude so that face formwork and railing posts can be arranged.
  • the side members over a support in the form of a beam with e.g. Cantilever steel tube supports. If the cross member were not secured upwards in the area of the side member, there could be a risk that the cross member tilts out of the side member with all its consequences for the people below the ceiling.
  • the cross members must be arranged at any arbitrary position in a longitudinal member or, for example, between two ten side members can be placed. Due to its design, the cross member end 7 cannot be hooked in a horizontal position between the upstanding edge 5 and the protruding upper flange 9 of the side member. If the cross member is only to be hooked into a longitudinal member at one end (see FIG. 2), then this can be carried out in the manner according to FIG. 5. After the cross member is hooked at one longitudinal end, the other end is raised according to arrow x. Once in a horizontal position, the connection is automatically secured.
  • a cross beam can be used which is shaped such that it can be brought into a first position rotated about its longitudinal axis and in a horizontal plane between the webs of the two nearest longitudinal beams ( Figure 3 , 3a) and then secured by rotation about its longitudinal axis between the upper flange 9 and lower edges 6.
  • the cross member 2 is provided with a securing part of a e.g. provided from the figure 6 form.
  • the selected solution has a cross member 13 on which an end plate 15 has a rectangular triangular shape, which has a long side 11 and a short side 10.
  • the cross member 1 is hooked with its long side 11 over the edge 6 of the supporting flange 5 of the side member 1, and by turning the cross member 2 about its longitudinal axis, the upright long triangular side 11 becomes the cross member in the side member 1 between the edge 6 and secure the upper flange 9.
  • the end plate of the cross member hooks over the edge with its short rectangular side 10.
  • the cross member end can be fastened to the cross member with, for example, a bolt connection 16.
  • a bolt connection 16 By now adjusting the position of the cross member 7, the upper side of the cross member moves into a different plane.
  • the illustrated Embodiment has only one connecting bolt 16, which (by rotating the end 7 through 180 ° about the longitudinal axis of the cross member) can be chosen between two different planes of the cross member 2 with respect to the upper side of the longitudinal member.
  • the location of the connecting pin 16 is chosen such that the upper surface of the cross member 2 is in the same plane as the surface of the side member 1.
  • the cross member 2b By turning the connecting bolt loosely and turning the cross member 2 about its longitudinal axis through an angle of 180 °, the cross member 2b is obtained with the upper side in a lower plane than the upper side of the cross member 1.
  • the formwork panel In the area of the cross member 2a can the formwork panel is placed on the side members and cross members. With the cross member 2b, a formwork panel can be placed between the longitudinal members, which panel has such a thickness that the upper side of the formwork panel lies in the same plane as the upper side of the longitudinal member 1, so that a flat formwork surface is obtained.
  • the invention is not limited to use only in the case of longitudinal beams which are already firmly arranged parallel to one another. It is also used for hooking a crossmember end into a longitudinal beam, the other end of a crossmember being finally brought to the same height as the first end from a lower level after hooking in the first end. In the end position, the cross member end is also secured in the side member.
